I'm trying to compare/contrast the surface gravity of Sonic's Möbius with that of Marioworld. There's an excellent article [1] that analyzed Marioworld's surface gravity across several games, wherein the mean average turned out to be 7.51(-) g. In trying to find similar material on Möbius, I've so far found only some material for generic differences between the games [2] and Source engine gravity [3] (after which I broadened my search to Sega Genesis's gravity in general, but no luck so far); Googling quite a few terms has been singularly unforthcoming.
I'm not asking in order to write code for game development. I'm curious about it for a much more mundane reason: I'm writing a fanfic in which Sonic noticed the difference immediately upon arrival. This means that I don't require 5 SD of accuracy (my OCD would love that, of course), but would like more than my own ballpark guesswork.
